T-E Pharma旗下免疫功坊長效型奧曲肽新藥TE-8214 第一期臨床試驗證實有效改善注射不適、抑制發病生化指標IGF-1
T-E Pharma旗下之免疫功坊 (Immunwork, Inc.) 今日宣布，其自主研發的長效型奧曲肽新藥TE-8214已於澳洲順利完成第一期臨床試驗。結果顯示TE-8214具備良好的安全性與耐受性、可達成預期藥理機制，且皮下注射輕易，不產生施打部位副作用。
TE-8214為免疫功坊運用專利平台技術開發之長效型奧曲肽 (octreotide) 類似物，經由在奧曲肽分子上連結含有兩條脂肪酸鏈的脂肪酸束，達成延長藥物半衰期，可應用於治療肢端肥大症與多種神經內分泌腫瘤所引致的病徵。上述兩類疾病常伴隨嚴重的內分泌失調，導致消化性潰瘍、嚴重腹瀉、氣喘、組織異常生長、關節疼痛與高血壓等症狀，若未妥善治療，將大幅影響患者的生活品質與壽命。
隨著全球對奧曲肽藥物需求的增長，近年來相關市場規模持續擴大，預估2030年將達100億美元。現有市售與研發中的相關產品，多為高黏稠度微粒或凝膠狀緩釋劑型，須使用19G或20G的粗針頭進行肌肉 (如Octreotide LAR) 或深層皮下注射 (如Lanreotide Autogel)，不僅施打困難，更易引發注射部位疼痛及結節等副作用，造成病患對治療的接受度與依從性明顯下降。
免疫功坊創辦人兼執行長，先前發明多項創新藥物的免疫學家張子文表示：「TE-8214 完成第一期臨床試驗是免疫功坊的重要里程碑，也為肢端肥大症與神經內分泌腫瘤患者帶來新希望。TE-8214具備高水溶性，可透過30G細針頭進行皮下注射，大幅減輕患者注射時的疼痛與恐懼感。未來我們將憑藉此關鍵優勢，積極拓展全球奧曲肽市場，為患者提供更安全、更舒適的治療選擇。」
TE-8214的第一期臨床試驗採雙盲、單劑量遞增設計，設有四個劑量組別 (0.6 mg、1.2 mg、2 mg及4 mg)，每組納入8名健康受試者，其中6人接受TE-8214，2人接受安慰劑(生理食鹽水)。整體結果顯示TE-8214耐受性良好，僅出現輕微不良反應，未觀察到任何嚴重不良事件。
常見的奧曲肽副作用為消化道不良反應，本試驗24位TE-8214受試者中，僅3人出現極輕微的消化道不適，證實TE-8214的安全性與耐受性表現優異。更重要的是，所有TE-8214受試者均未出現注射部位疼痛或結節情形，結果與安慰劑組的受試者完全相同，顯示TE-8214的劑型設計成功解決緩釋劑型的痛點問題。
此外，奧曲肽類藥物主要透過抑制體內類胰島素生長因子 (Insulin-like growth factor 1, IGF-1) 濃度發揮治療效果。在本次試驗的高劑量組別 (2 mg和4 mg) 中，12位TE-8214受試者中有10位 (83%)，其IGF-1濃度下降超過20%，顯示TE-8214具備顯著的IGF-1抑制效果，進一步支持其作為治療用藥之優秀潛力。
目前，免疫功坊正積極展開第二期臨床試驗的籌備工作，預計於2025年第三季在台灣正式啟動。我們期盼透過未來階段的試驗推進，加速驗證TE-8214的治療潛力，拓展其臨床應用與全球市場佈局，為更多患者帶來突破性的治療方案。

T-E Pharma's subsidiary Immunwork Announces Positive Phase I Top-Line Data for TE-8214, a Next-Generation Long-Acting Octreotide, Demonstrating Favorable Safety, Tolerability, and Potent IGF-1 Suppression.
·Pioneering Patient Experience: TE-8214, a highly water-soluble aqueous solution, enables pain-free subcutaneous injection with a thin 30G needle, eliminating injection site reactions seen with current therapies.
·Strong Pharmacodynamic Activity: Robust, dose-dependent reduction of disease biomarker IGF-1, with 83% of high-dose participants achieving a >20% reduction, confirming therapeutic potential.
·Significant Market Potential: Positioned for the US$10 billion long-acting octreotide market by addressing key unmet needs of painful injections and side effects associated with current viscous, thick-needle formulations.
·Phase II Initiation and Strategic Partnering: Phase II trial planned for Q3 2025; Immunwork is actively seeking strategic collaborations to accelerate global development and commercialization.
Immunwork, Inc., a clinical-stage biotechnology company developing transformative therapies, today announced positive top-line results from its Phase I clinical trial (in Australia) of TE-8214, a novel long-acting octreotide analog for the treatment of acromegaly and neuroendocrine tumors (NETs). The study met its primary objectives: TE-8214 demonstrated good safety, tolerability, and pharmacological activity, with pain-free subcutaneous administration and no injection site reactions.
A Next-Generation Therapy for Unmet Patient Needs
TE-8214 was developed using Immunwork's proprietary fatty acid modification platform, which extends the drug's half-life and increases water solubility. TE-8214's water-soluble, low-viscosity formulation allows for subcutaneous administration with a fine 30G needle, offering a dramatically improved patient experience compared to the current standard-of-care, which requires thick, viscous formulations administered with large 19G or 20G needles that often cause significant pain and injection site reactions. This innovation addresses a critical need for safer, more patient-friendly long-acting therapies in a global octreotide market projected to reach US$10 billion by 2030.
Phase I Clinical Highlights TE-8214's Differentiated Profile
The randomized, double-blind, placebo-controlled, single-ascending dose study enrolled 32 healthy subjects (24 receiving TE-8214 and 8 receiving saline) across four dose cohorts (0.6, 1.2, 2, and 4 mg).
Exceptional Safety and Tolerability: TE-8214 was well tolerated with no serious adverse events reported. Notably, no TE-8214 recipients experienced injection site pain or nodules—results identical to placebo with saline — demonstrating a clear advantage over existing therapies. Gastrointestinal side effects, often seen with octreotide, were minimal: only 3 of 24 TE-8214 recipients reported very mild gastrointestinal discomfort.
Potent and Sustained Pharmacodynamic Activity: Octreotide drugs mainly exert their therapeutic effects by suppressing insulin-like growth factor 1 concentration in the body. In the two highest dose cohorts (2 mg and 4 mg), 10 of 12 participants (83%) achieved a >20% reduction in insulin-like growth factor 1, confirming robust biological activity and validating its therapeutic potential for Phase II studies.
“These Phase I clinical trial results confirm TE-8214's differentiated profile: TE-8214 is highly water-soluble, can be administered subcutaneously using a fine needle, significantly reducing injection pain and side effects for patients,” said Dr. Tse-Wen Chang, founder and CEO of Immunwork and a pioneer of anti-CD3 (OKT3) and the inventor of anti-IgE (Xolair) for asthma and allergy. “By solving the fundamental formulation and administration challenges of current treatments, we have created a product with the potential to become the new standard of care. TE-8214's profile—combining ease of administration, superior tolerability, and strong efficacy—positions it to capture a significant share of the market and, most importantly, vastly improve the quality of life for patients.”
Strategic Outlook: Advancing to Phase II and Seeking Partnerships
Immunwork is preparing for a Phase II trial of TE-8214 in Taiwan, planned to start in Q3 2025, to further evaluate the efficacy and safety of TE-8214 in patients. The company is actively pursuing strategic partnerships with pharmaceutical leaders to accelerate late-stage clinical development, navigate global regulatory pathways, and maximize the commercial potential of TE-8214.
